Abstract

 Reverse running centrifugal pumps are  an effective source of reducing the equipment cost in small hydropower plants. The manufacturers do not provide any information on the performance and fow characteristics when pumps are operated in turbine mode. Lack of Pump as Turbine (PAT) performance data is a signifcant barrier to the wider use of PAT. Application of Computational Fluid Dynamics (CFD) is a recent attempt for predicting the performance of PAT. CFD analysis is an effective design tool for predicting the performance of reverse running operation of centrifugal pumps. But some deviationsstill exist in experimental and CFD results of reverse operation of pumps. Future works in the feld of computational analysis can further improve the prediction of pumps in reverse operation.

Key words:  Pump as Turbine (PAT); Computational Fluid Dynamics (CFD); Pump
